Feature Normalization

See original GitHub issue

I would like to add a threshold to the feature normalization.

Explanation taken from here: https://www.audiolabs-erlangen.de/content/resources/MIR/chromatoolbox/2011_MuellerEwert_ChromaToolbox_ISMIR.pdf

To avoid random energy distributions occurring during pas- sages of very low energy (e. g., passages of silence before the actual start of the recording or during long pauses), we replace a chroma vector x by the uniform vector of norm one in case |x|p falls below a certain threshold…

Anyone against adding a this parameter to the normalize() function?

Agreed. I think we’ll want to change the api to reverse the interpretation of axes.
